A. Shifts equilibrium to the left
B. Shifts equilibrium to the right
C. No effect on equilibrium
D. Increases reaction rate
Answer: Shifts equilibrium to the left
For the reaction PCl5(g) ⇌ PCl3(g) + Cl2(g), what effect does increasing Cl2 concentration have?
Additional Information: Increasing Cl2 concentration shifts equilibrium to the left to favor PCl5 formation.
